What are the characteristics of a femme fatale in film noir?

The characteristics of a femme fatale in film noir often center around the archetype of a seductive woman who leads men into perilous situations. This character is typically portrayed as alluring and mysterious, using her charm and sexuality to manipulate those around her, particularly male protagonists. The femme fatale embodies themes of danger and intrigue, often being the catalyst for the male character's downfall or moral corruption.

Her presence adds complexity to the narrative, reflecting the darker elements of human nature and the consequences of desire. By presenting a woman who is both captivating and potentially lethal, film noir explores themes of sexuality, power, and betrayal. This archetype significantly differs from nurturing or supportive characters, as well as male heroes who typically engage in acts of bravery and resolve conflicts rather than creating them. The femme fatale is essential in highlighting the genre's overall tone of cynicism, moral ambiguity, and the tension between desire and danger.
